INPUT OBJECTS
E-STOP (emergency stop)
E-STOP function block verifies an emergency stop device
inputs status. If the emergency stop button has been
pressed the output is 0 (FALSE). If not the output is 1
(TRUE).
Parameters
Input type
:
-
Single NC – allows connection of one-way emergency
stops
-
Double NC – allows connection of two-way emergency
stops.
Enabled reset
: If selected this enables the request to
reset each time the emergency stop is activated.
Otherwise, enabling of the output directly follows the
input conditions.
There are two types of reset: Manual and Monitored. When Manual is selected the system only
verifies the signal's transition from 0 to 1. If Monitored is selected the double transition from 0 to 1
and then back to 0 is verified.
Î
WARNING: If the Enabled Reset is active, a consecutive Input has to be used. Example:
Input 1 and Input 2 are used for the functional block, then Input 3 has to be used for the
Reset Input.
